What is the equation of a line with a slope of 4 and passing through the point (1,-1)?
\n" ); document.write( ":
\n" ); document.write( "Use the point/slope form: y - y1 = m(x - x1)
\n" ); document.write( "where
\n" ); document.write( "x1=1
\n" ); document.write( "y1=-1
\n" ); document.write( "m=4
\n" ); document.write( ":
\n" ); document.write( "y - (-1) = 4(x - 1)
\n" ); document.write( "y + 1 = 4x - 4
\n" ); document.write( "y = 4x - 4 - 1
\n" ); document.write( "y = 4x - 5
\n" ); document.write( ":
\n" ); document.write( "confirm this, substitute 1 for x and see that it will = -1 \n" ); document.write( "
\n" );
